HORACE CHRISMAN, or :ansnwoon shutting ofi the supply of water "to the access may be and useful Invention PARK, PENNSYLVANIA, Assrenoa To PITTSBURG METER COMPANY, OF EAST PITTSBURGH, PENNSYLVANIA, A CORPORATION OF i PENNSYLVANIA,

To all whom it may concern Be itknown that I, HORACE CHRISMAN, a citizen of the United States, and a resident of Edgewood Park, inthe countyof Allegheny and State of Pennsylvania, have made a new in Meter Systems,of which the following is a specification.

This invention relates to Water distributing systems and is a div'sion of the appli-- cation filedby me in the nited States Patent OfiiceAugust 29, 1910, and givenSerial N umber 57 9,503.

One object of the invention is to produce means whereby access maybe had toa portion of thesystem without the necessity of system. i I

A further object is to provide a meterlor a valve casing tems, inwhichmeans are employed whereby had to the 'meterjonto the valve without the necessity of shuttingofi" scribed, and illustrated iIr-the the water or in any way obs'tructingits 'flow.

for water distributing sysmeter 15 so located casing and is axially 1 of the "port 6. I

this application filed January understood, I will first briefly describe the water delivered by the system and since the flows are small, the most accurate results are obtained by positive registering meters; that is, by meters through which the water to be measured passes. Such meters are objectionreasons, when located in i Patented Dec. 1,-1914.1

meter for registering the small fiow is ordinarily'located in a bypass, which extends t around anemergency valve located in the main and adapted to open voluntarily during large flows;

normal and operative posiwhen the rate offiow is increased by an abnormal demand for water. Both arrangements are employed with a deor a positive registering" and arranged in the main that it will intercept the small fiows ofwater and cause them'to pass through it, and will swing from its I tion so as to'provide asubstantially unobstructedpassage tector, which indicates in one Way or other that the registering meter has been rendered inoperative.

I have illustrated my invention in connection with a meter system embodying the *latterarrangement, that is, a meter which is adapted to move whenthe flow of waterthroughthe main exceeds'the normal. I i

to an inoperative position The; numeral 4 indicates 'a casing which casing and which lsprois in effect a-valve vided with flanged inlet and outlet ports 5 and 6. The ports of the casing are adapted to communicate with the mainof a water distributing system and are so arranged that the water traversing the main will pass "through the casing. vided with a reentrant flange 7, which pro-' The inlet port 5 is pro- 8 formed Within the jects into a chamber alined with'the flange A registering device or meter 9 is suspended within the chamber 8 and is so arranged that it seats on the inner edge of the flange 7, as shown in Figures 1. and 2, and

intercepts the water traversing the casing during small or normal flows through the main, and swings to an inoperative position and provides a substantially unobstructed passage for the water through the casing 4:, when the flow of water exceeds the normal. Any type of metermay be employed; the meter shown, however, is of the wabbledisk type and is provided with a casing 10 which incloses the disk and is provided with inlet and outlet ports. A substantially circular disk or plate 11 is illustrated as beingintegrally formed with the casing 10 and is so located that it seats on theinner edge of the flange 7 when the meter 9 is in the operative or normal position. A suitable opening (not shown) is provided in the disk 11, which communicates with the inlet port 5 of the casing meter. A ported cap 12 is mounted on the disk 11 and is adapted to cover and to. some extent form a shield for the inlet port of the meter. The cap provides suflicient communication between the inlet port 5 and the meter to accommodate all normal flows of water. The discharge port of the meter is not shown, but it is so located that it communicates with the chamber 8. Vvith this arrangement, the water traversing the main, during the normal flows, passes through the meter and is then discharged into the chamber 8 from which it is delivered through the port 6.

suspending lugs 13 are provided on the plate 11 and the meter is suspended by means of them on pins 14 and 15, which are mounted in suitable lugs provided on the casing 4. The meter, with the plate 11 is in effect an emergency valve, since it covers the port 5 during normal flows and opens voluntarily to provide an unobstructed passage through the port during abnormal flows. A cover is provided for the casing l and is adapted to be secured in place on a flange 16 provided on the casing. U The cover is so constructed that it permits the meter to swing unimpeded. 1

One of the principal features of my-in vention is the production of means whereby the cover of the casing 4 may be removed and the meter 9 inspected, repaired or re,- moved without the necessity of shutting off the flow of water through the main.-

In the illustrated embodiment ofmy invention,'I, provide a sleeve '17 which isnormally located .in-the port (Sand is capable of beingmoved across the chamber 8 so as to form a direct means of communication between the ports 5 and 6, when the meter?) is swung'to an inoperative position The sleeve 17 is provided with gear teeth 4:, and with the inlet port of the ably packed a guide would be necessary if. a narrowjajck were employed. In addition to this the friction surface between the sleeve and the walls of the port 6 is reducedby providing the gear teeth on the outer surface-lof the sleeve, A guide or support 20-;islocated within the chamber 8 and is adapted to guide and support the sleeve in itsmotion I across thechamberand .to hold'it in place after it has bridged the chamber.v

The pinion 19 is located in. a recess formed within the casing A and isym llnted on a shaft 21 which extendsthrough a suitjects beyond the casing 4:. Theouter end of the shaftis arranged to receive a crank or gland and bushing22 and pro-.

operating handle, by means of which.the

pinion 19 may be turned for the purpose of moving the v sleeve .17. 'The supporting pin 1 I 15 of the meter 9 also extends out ofthe casing A, through suitably packed gland and bushing, and.is' arranged :to'receive a crank or operating handle,- which may be employed n raising the. meter from an .op-.

erative position, as illustratedin Figures 1 and2,-to-an inoperativepo'sition, as shown in Figure3. An arm 23 ismounted on. the

hen it is desired to obtainaccess i position when. the shaft 15 is meter. 9, the. shaft 15 is turned so as to swing the-meter to the inoperative position, illustrated in Figure 3, the shaft 21 issthen turned so as to move the-sleeve 17 across the chamber 8 and into engagement with .the

inner end of the rentrant flange 'Z. The

top'fofflthe casing A can then be removed without the necessity of shutting off the flow of water through the casing, since-the water willpass directly through' the sleeve 17 insteadof the chamber 8. I 1

T he outer-Lend of theflsleeve '171is provided with an annular flange 25 which is adapted to formed in, theend of the flange7, when the sleeveisimoved to engage the proiect into an annular recess 26,
